Development of a Silicon Nitride Ceramic Material Featuring a Higher Resistance to Thermal Shocks at High Temperature
With the global trend towards the reduction of emission on carbon dioxide, one of the key areas to achieve this mundane task would be in reducing heat energy loss in the production processes used in such industries as steel and the non-ferrous metals, through extending the life cycle of materials that are used for protecting tubes, ladles, stalks, heat tubes, as well other parts that are being used in casting process. One ideal candidate to achieve this is silicon nitride with excellent high temperature and thermal shock characteristics, however the material lacks sufficient heat resistance as well as resistance to thermal shocks, preventing it to be used in casting iron, etc, where it would be exposed to much higher temperature and sever thermal shocks than for example, in aluminum casting processes. Based on this fact, group of researchers at AIST, with collaboration with Mitsumi Mining & Smelting have successfully, developed a silicon nitride ceramic material which shows a significantly higher thermal shock resistance and strength at high temperatures in comparison to conventional silicon nitride ceramics.

We all heard of IC Tags used for quality control and inventory and merchandising of some sort but you probably never heard of IC tags that can be embedded into shipbuilding pipes. Well, there are around 6,000 to 10,000 shipbuilding pipes go into constructing a ship, and over half of them are hot-dip galvanized otherwise known as plated for preventing corrosion. The pipes can easily be identified through printing or engraving on the pipe, however physical identification of these pipes after they are plated can be only possible by visually looking at their shapes and dimensions for the sorting process, resulting in human errors and inefficiency in shipbuilding operations. Use of IC tags in this process would provide an efficient way in sorting the pipes, however the guaranteed temperature limit for IC tags was originally 100 degrees Celsius, which make it impossible to be used under conditions for plating where temperatures can reach close to 450 degrees Celsius. In response to technical challenge, Toppan Printing has developed a prototype ultra heat resistance IC glass tag which can withstand a temperature of 450 degree Celsius. Read more
Hamamatsu Photonics has developed a new high-temperature photomultiplier tube (PMT) for oil well logging featuring an 8 times longer life time than conventional PMTs. The newly developed PMT in addition to its extended use offers the ability to drill in deeper geological layers with high temperatures. Read more
Well the next best thing to Full HD in display technology before reaching true 3D display ear is 4K panels offering a resolution of 8.85 mega pixel which is four times the resolution of full HD (1920 x 1080) ideal for high resolution demanding special applications such as industrial design, architectural design and simulation plus for use in presentation in projecting a four full HD images at the same time where market is seeing a continued expansion. To meet such market need, Seiko Epson made an announcement on development of world’s first 4K compatible high-temperature polysilicon (HTPS) TFT liquid crystal panel targeted to be used for 3LCD projectors.

Seiko Epson made an announcement on production of Ultra-Compact, High-Resolution HTPS TFT color liquid crystal panel for Electronic viewfinders. The new high temperature polysilicon (HTPS) TFT color panel measures only 1.2cmm diagonally and it offers SVGA (800xRGBx600) resolution for a total of 1.44 mega pixels. The new panels to be used for electronic viewfinders form mid-to high-end Digital Single Lens Reflex (DSLR) cameras. The new development is to fulfill the consumers’ need for smaller and thinner DSLR cameras with video and other features.
The new panel offers a high resolution and fidelity required to replace optical viewfinders and to focus the image in addition to re-creating a smooth gradations and a natural softness by incorporating an analog driver. Read more
